How to create a custom font with a subset of the icons?

[gr2m]

Is there anyway I could create an own font based on the SVG vector graphics, with only the icons used by my app? That would reduce the file size quite a bit.

Agreed. If you look at markup within the SVG file, you'll see a series of glyph elements with a unicode attribute. You could reverse engineer what each glyph is bound to and remove the ones you don't need. It's a hack, but it should work.
