client /etc/lts.conf not honoured

While debian doesn't include much ltsp docs, googling leads me to believe
that putting
NETWORK_COMPRESSION=False
into my client's /etc/lts.conf should disable ssh compression.
However, ssh is always being invoked with the -C option.
I think /usr/sbin/ldm needs patching thus:
diff ldm.orig ldm
193c193
< if 'NETWORK_COMPRESSION' in os.environ:
---
> if 'NETWORK_COMPRESSION' in os.environ and get_config_bool('NETWORK_COMPRESSION'):
or at least that's what I've done locally and it seems to work as intended.
(Although I imagine pushing the existence test down into get_config_bool,
with the not-present default value as an additional argument might be a
superior approach).
[I just have one 1Ghz Via Mini-ITX client; for a graphics intensive app I find
while disabling compression raises bandwidth from ~10Mbit to ~25Mbit, and
framerate doesn't actually increase much at all (+25-30%?), the sshd on
the 2.4GHz P4 server drops from 50% CPU to 10% (ssh time on client pretty
much the same). This is a better setup for me than with compression; I just
mention this in case you were planning on getting rid of control over compression
completely!]
