Alan,

Lots and LOTS more :-)

No, and not nearly so.

The volume in the various streams is increasing rapidly.  We currently
recommend that IDD users have a 200 MB LDM queue so that which stores
about an hour's worth of data (which is not quite at 200 MB/hr but
will get there some time soon).  So, as a reasonable measure, I would
say that the data you could be receiving is 200 MB/hr * 24 hr = 4.8 GB
per day.

>Thank you

Sorry that this wasn't responded to sooner.  I had forwarded it to Robb
not realizing that he is not in the office this week.
