It even mentioned hobbyist clusters over the internet as a practical implementation. ;)

I'd be up for trying a cluster over the internet   

Do you have the bandwidth for a high-performance one, or would we end up with a high-latency constantly-exploding one? ;)


My London site does about 1.5 Mbps up, 17 down, local (UK) ping of about 20-30 ms, up time at the moment is 57:13:59, but that's because I rebooted the router after some changes.

On a related note: How hard would it be to modify Johnny's bridge to carry LAN-over-IP traffic? Not sure I want to upgrade my boxes to 8.4   

We could do OpenVPN Layer 2 bridging.   Can it be made to handle the multicast bits?   My ISP here (512k up!) blocks L2TP proper unfortunately.

My mail server on the other hand has plenty of bandwidth and blocks no protocols, but it's running low on RAM.

My primary VPS would need another IP and a little bit of MAC hackery, but I might be able to get my provider to allow that.   It runs FreeBSD and I don't think any alpha simulators run on it natively   alphavm-free may run in linux binary compat, though...
