Hi Sebastian,

can you tell us a bit more?

You be recording with XO-1 units... using Record in Sugar? What
version of Sugar and Record? Or you'll use gstreamer directly to the
server?

One possibility would be to write to an NFS share -- but 'realtime'
recording of videos over wlan is tricky and likely to fail. The wlan
connection can easily get interference from external sources or just
contention (from too many users on the same AP or frequency).

If it's possible, recording locally and then having a backup or
explicit upload/copy is the most reliable method.

Local recording on an XO-1 is limited by the JFFS2 storage -- if you
are prepared to use something other than standard Record, you may be
able to capture at high resolution and store without compression (or
with minimal compression) writing straight to a fast USB Flash
storage, or an SD card.

This will give you the best starting quality -- which you'll need as
you're intending to use this for a documentary.

cheers,
