I wish I could remember the name of the BBS software I set up for the CCAUG (Corpus Christi Amiga Users Group) back in like 1990 or 1991 or so. It let you embed IFF images for menus and image posting if you were using a companion terminal program to access it. Slow as hell at what was, at the time, fast modem speeds. A lot of us suffered through it just to say we had something "better" than ANSI graphics or at least more unique.
A local programmer who had developed the most amazing Commodore C64/C128 BBS software, which the name also escapes me other than his handle, The Dragonmaster (*), was supposed to do up his magic for an Amiga board, and I was anxiously awaiting that to swap our Amiga board over to, but I'm pretty sure I went away to school before that happened. His board and companion terminal program were fast by comparison because his used sprites client side rather than transferring over loads of bitmap data.
Musicterm, that was his terminal software, because he was a musician and his BBS software let you embed music code into messages that would be interpreted client side. Genius guy. I always wanted to see what he'd come up with once he got his teeth sunk into the Amiga.
edit:(*) found it, Darrel Spice Jr., Spiceware and the C64/128 software was indeed MusicTerm.
