- Well, yes, except it's not called _PC_nfs on the Arc. (-8

- It would be a bit hard to hack if it was a read-only nfs partition, too...
- The files would really have to be downloaded to a hard disc, if the server was
- to stand any chance of servicing more than one viewer at once. My thoughts were
- that Acorn, in particular, will presumably have them all on a hard disc
- somewhere anyway.

- I think your JIPS link is slower than ours, then. The bandwidth required would
- be 60Kb/sec for the 12.5fps demos, or twice that for 25fps (obviously). I
- reckon more than a few sites can stomach that.
