Of course, which is why a demo would be a great way to gain some traction among real Commodore 64 and Commodore 128 users. There are plenty of big Commodore BBS systems connected to the internet. Most of them support Punter or X-Modem, so downloading to your Commodore setup is really easy.
Excellent! Please see this Lemon64 thread for a list of online BBS systems - I'd suggest getting in touch with Particles BBS.
