That sounds reasonable. You'd get some real multi-tasking in that way.

I am interested in this.

Do you have a "file server" program that would look like a disk drive to 
the Commodore side? I need something that can serve a 4-megabyte file to 
a Commodore Vic-20. The cleanest solution would be to have a serial bus 
device. I do not need any 1541 or fastloader emulation, not even REL 
file support. Just the standard disk routines, or maybe JiffyDOS.

Why 4 megabytes, you might ask? I want to be able to program the Vic 
Flash Plugin <http://www.iki.fi/~msmakela/8bit/vfp/> in-system. We now 
have parts for some 15 boards, just waiting for assembly and a wooden 
case. I tested the software on the years-old prototype last summer. It 
is supported by VICE.
