I need to find a graphics plug-in (commercial or shareware) that has support for a multi-bit alpha channel in Delphi. Any good suggestions?

or you could make you own, you just need have *two* bitmaps, a 24bit & a 8bit.  Checkout the bitBlt parameters for drawing options, and (for special cases) maskBlt
