Your answer will depend on two things.
1) where the closet door is.
- If the door is in a low traffic area, such as an adult's bedroom, a guest room, or such an eggshell finish is great. If by chance the door gets a smudge of dirt on it you can wipe it with a damp cloth to remove the dirt, but scrubbing it will damage the surface.
- If the door is in a high traffic area, such as a main entrance, mud room, or child's bedroom you may find the semigloss a better bet as you can give the surface repeated cleanings without effecting the surface.
2) your personal aesthetics
- If you want a seamless look from walls to doors, or just don't like the look of a semigloss and are willing to either repaint a bit more frequently or be extra careful when you clean then by all means use eggshell.
- If the thought of a scuff showing gives your the shivers then semigloss is your way to go.
May I suggest a third alternative? Most paint manufacturers now make at least one sometimes two or three, gloss levels between eggshell and semigloss. Pearl, and /or satin are the most common. As gloss factors go up, the hardness of the surface increases, so these would allow some what more cleaning potential and still keep the "shine" down.
If you mix a flat and semi-gloss 1:1 you should end up with a paint in the eggshell range. Mix the same paints 1:3 and you should end up with a satin. Experiment with small amounts to get the desired gloss.
Yes, you can put polyurethane paint over eggshell in latex or eggshell in oil.
Yes, eggshell paint is good for doors.
No, because eggshell paint is intended only for indoor use, like kitchens or bathrooms. For exteriors, use paint with a satin finish.
You can, but don't need to use additional primer.

Latex and acrylic (both water-based paints) do come in a semi-gloss finish.
Yes, as long as the surface is free of dirt, wax and grease, and the eggshell and satin are both the same type, ie latex or oil, then you should have no trouble at all painting a satin sheen paint over an eggshell. Also, if the base is water based and the topcoat is oil, that will work fine too.
There are flat paints that are made to go over semigloss paint. Many inexpensive flat paints will peel almost immediately when laid over semigloss. The most common solution is to roughen the surface of the semigloss (sandpaper, sandblasting, steel wool, or trisodium phosphate). The actual requirement is to remove alkyds which migrate to the surface of some semigloss and gloss paints. The alkyds make it impossible for latex or acrylic to bond to the surface underneath. You also have to remove buildup of dirt, mildew, etc. Most primers are suitable for recoating semigloss. Read the label. A layer of primer followed by your flat paint is generally the best solution if the surface is relatively clean. Benjamin Moore Fresh Start interior / exterior acrylic primer is one example of a good primer for this application.
no it isn't
I would recommed satin or eggshell. Satin and eggshell paint or both easy to wipe/clean and better to withstand multiple cleanings.
Doesn't the amount of varnish in the paint make the difference?
Two entirely different things. Acrylic is a type of water-based paint (usually latex/acrylic) and eggshell refers to the sheen (ie flat, satin, eggshell, semi-gloss, etc...). Also some people assume eggshell refers to a certain color, however with many paint companies, the term "eggshell" refers to the sheen texture (feels like an egg shell) and not the color of an egg (which, of course, depends entirely on the type of bird if came from). :)
