Well, we ran StorageService.bulkLoad via JMX.
According to http://www.datastax.com/dev/blog/bulk-loading  this should hav=
e the same effect and can be done on the same machine:

"Because the sstableloader uses gossip to communicate with other nodes, if =
launched on the same machine that a given Cassandra node, it will need to u=
se a different network interface than the Cassandra node. But if you want t=
o load data from a Cassandra node, there is a simpler solution: you can use=
 the JMX->StorageService->bulkload() call from said node."

You said you tried restoring a snapshot via bulk loader, did you actually r=
un sstableloader?
