In general I don't think this would > be a really difficult project. Appletalk runs at about 28Kbaud I guess. The best chip to use for it is the Zilog 8530 (or 8030 - same chip, different bus). This was actually discussed previously here, the easiest way to do it is the write an Appletalk little box which sits of an Amiga serial port, that way everyone can use it. Well, if I had docs on Appletalk..... (ie. I've got the hardware (8031/eprom/ram/8530) but don't know how to setup the chips for Appletalk, or the Appletalk framing works... hint hint.. send me docs!)
