Yes, it will log the phase data stream and create the same set of plots 
from it as with other data.  I think John has mentioned some issues 
keeping the connection open over long collection intervals, but I 
haven't seen any issues.

However, in my Perl code I ended up increasing the TCP timeout to a 
quite large value -- the data seems to be sent with varying delay and 
sometimes pauses for a while, presumably while the system is occupied 
doing something else.  A long timeout keeps things running during the 
pauses, and no data seems to be missed in the process.
