I have a bunch of other stuff on my list of gadgets before I get me an iSi soda siphon, but here is a link to that site.
iSi has a recipe site called espumas.com (espuma = foam in Spanish) where they offer a few recipes for espumas as well as sauces, etc., but they are big on gelatine sheets, not egg whites. Also, their espumas are more food oriented than drink, which is probably why they are big on gelatine. It seems to make a heavyish foam.

The reason I first got interested in the soda siphon was that I heard about coconut milk foam, which uses just coconut milk and, as an optional add-on, sugar. If you don't have any recipes, you might try the iSi basic recipe structure (they have an interesting mango foam) and substitute egg whites for the gelatine, guessing on quantities.

There's a pre-made foam called Frothee, but I understand if you're desperate enough to consider it, fight the urge.
