Yep. As I mentioned in the previous email to you:
I have been in contact with Martin at VMS (http://www.vmsrebreathers.com/
they took over the Sentinel from VR) about opening up the protocol to 3rd
party (such as libdivecomputer), but he insists on keeping it proprietary
and creating his/their own desktop software.
Beats me why, since it is in no way in their interest. I did plead that he
would at least consider including an export function to that software, so
that Sentinel users could then continue using their favourite log software
(ie. Subsurface).

VR Sentinel.
However the intended import-feature is totally useless to me, since I'm
currently relying on a gauge-mode Suunto to record all normal dive
information, sans the gas consumption.
This means that unless the software provides me a way to define the dive
concurrent cylinder use (which would anyway be required by the sidemount
divers), then I would need to manually download the dive data from the DC,
add the cylinder information (of which I only have the start and end
pressure), then import it to Subsurface.
This seems like a waste of time since the format would be something
Suunto-ish, with multiple concurrent cylinders in use. Nothing that exists
in the real world.
Until VMS defacto provides a software which enables me to do export, my
intermediate solution will be to get a DC which understands setpoints
(Petrel or NSTC2/3), and trade the HelO2 for that, so that I get at least
approximate data out. This however still does not cover the fact that I
still will need to fill the cylinder information manually.
And yes, I intend to help in any way I can, since Subsurface is my choice
for divelogs.
