I didn't read trough the whole article, but openSSI seems to do the
clustering at process-level (somewhat like Mosix).
If this is the case: Technically you could probably run a webserver on
top of such a cluster, but I doubt it would be a good idea as it will
probably have quite a bit overhead which doesn't seem necessary for a
Apache cluster. In the end the cluster would either need some really
beefy hardware (especially network for the I/O I guess) and/or won't
deliver the performance you would expect.
A dedicated loadbalancer is probably the better solution as it doesn't
add much overhead - its only job is to distribute incoming requests.
Anyway: please correct me if I'm wrong! ;o)
