Re: RE: Wish List

Dear Peter,

Thanks for your suggestion.  The code snippet you provided is more "object
oriented" than mine and I like that approach better.  Please remember that
http, xml, php, and other protocols are just markup languages with different
DTDs (descriptions of how they should behave).  I hope that RIMCP will
someday support over a dozen languages, including C/C++, Pascal, ADA, etc.
Keep in mind that the code snippet you wrote is nothing more than a "human
readable set of strings" that can easily be "passed" via a custom cable
interface or through a broadband internet connection, without interfering
with other peoples' use of the internet( or being interfered with by the
internet).  What is done with those strings depends on the ability of our
RIMCP "support software" to determine the language of the transmission (best
to do with descriptive headers) and its ability to compile and run that code
"interactively" on the receiving CPU/platform.

The whole "key" to RIMCP is the "ability to learn new things", which your
code snippet clearly points out....thanks!

Corba has experienced some problems in communication due to firewall
interference.  My preference would be to develop RIMCP to interoperate with
http "transparently"...so that no roadblocks will be encountered.

In developing our own DTD, I need all the "feedback" I can get from other
experts in the robotics and programming fields.  Your suggestions will help
us make sure that RIMCP remains flexible, unblocked by firewalls, and
extensible enough to support all new technologies in the field of robotics.

Thanks so much for your comments.

Sincerely,

Arthur Baldwin
