Is the source code freely available?
If we can recompile, our users (at the Bureau of Meteorology, Melbourne,
Australia)
may be interested in increasing the limit for binary requests to up to 2G,
on suitable servers.

Nothing really , just using the link as an installation test
(not being aware that there are separate limits for text and binary).
It is however, difficult, to persuade users NOT to follow
links if they are there, then to persuade them that 'code 403'
is not an error, and finally to find a proper answer when they
make (unfair) comparisons with file size limits of ftp and http
(as a rule, users expect new protocols to supersede the old).
I believe this is critical for wide spread adoption.
Regards,
Fanel

Hi Fanel:
The latest version of TDS has limits of 500Mb and 50 Mb, respectively,
for opendap binary and text requests. This is hardwired in at the
moment, but we will make it user-configurable.
What are you doing with such large ascii requests?
