Cliff sez: There's a new software shop here in Mill Valley, of all places. They've made
a pretty cool little "virtual private network for the rest of us" … called Grouper and here's a bit about it:
Current release version is in beta. Runs only on Win2000 and XP. Requires
broadband.
With the client installed, you can create groups of up to 30 members and
invite people to join them. The invitation includes the client.
Each peer can choose to share selected files. The client includes group chat
and 1-to-1 IM.
You can download all but MP3s. Those you can only stream. I know that will
be a point of contention, but it's not meant primarily to be a source of
free music. I think it's more for groups of friends, family, classmates,
associates who share photos and other large files. Link
