Hello Jón,

I think that that is an admirable endeavor to start on but most of
what you describe there has already be done by several groups and at
least two of them are in the public domain and free.

I think that it would be far easier to write the missing modules for
the core Earthworm system than to reinvent something that already works
well and is in wide use.

Right now you can take the data from the PSN serial card (and others)
and go directly into Earthworm or Seiscomp over a TCP/IP and in either
of those systems you can do most of the things you list.

Jon, you can find more information for the two systems I mention at
these URLs:

Warmly,

Angel
