Yep, I do this since 2003. Though not with Linux, yet, but Win32 on an
RME Multiface.

Sampled pianos, strings, some synths.

I started on AMD Athlon xp1600 (iirc) with 1GB RAM and I'm now on AMD
athlon 2x2GHz laptop with 3GB RAM.

What can I say? It works. The audience varies from 150 to 4000 people,
and I trust my system, despite it's Windows. ;) I clearly wouldn't even
enter the stage when I'd doubt system stability.

This said, Linuxsampler was the most useful virtual instrument I found,
but I'm really missing my Hypersonic2. This comes very close to a
typical keyboard workstation with lots of _decent_ sounds like Korg
Triton or Yamha Motif.

I then bought a Korg microX as the primary sound engine for my ardour
based studio setup. It's around 450 Euro, it delivers the Triton sounds,
it's hardware and it's approximately the price one would have to pay for
a good virtual instrument. It's the confession that HQ virtual
instruments on Linux (besides LS) won't happen any soon.

You don't need 9ms, I use 12ms, and I would claim I'm not lagging behind
the drummer. ;)
