Tkined - A few questions

We are using Scotty/Tkined to develop and prototype some network
troubleshooting tools. Scotty is a wonderful tool - many thanks to
Juergen Schoenwaelder and all of the developers. Now that I have used it
and programmed some custom procedures I wanted to post a few questions.

Data Import: BTW I have written a Tkined script that imports custom data
and draws a map. I know I could've genned a config/tki file (like form
the Save command) but I wanted to reserve the option to mix in
additional discovery commands. The script is based on ip_discover.tcl
even though I ended up disabling most of the features. It also includes
some code from ip_layout - it is fun looking at the german language
source code! The script is pretty simple, but let me know if anyone is
interested in how this was done.

Bones: I was wondering about the Bones integration. There is not much
about this in the newsgroup and I see that it is not really integrated
in the sense of a direct database backend to the process of: Discover
and/or Data Import; Draw the map; Add/merge attributes; Save to
database. Question: Is tighter database integration forseen in the new
version or is someone working on such a project? I am new to TCL so
maybe I just don't "see" it. I suppose you could just do :
foreach object [inet retrieve] {decompose_and_insert $object $database}

Telnet/Expect: I have been informed that security-conscious customers
are said to only allow "telnet" protocol through (via dialup or the net)
for troubleshooting purposes. If this is a common scenario (is it?),
then it is unfortunate to have to forego every protocol except for
telnet. So, question: has anyone developed scripts to drive the
performance meters/bar-charts through tcl/expect/telnet processing
(instead of rpc or SNMP)?

Remote: How does the Remote/Tkined work (in manager.tcl-
ComAccept/Listen/Connect) ? Does this mean that you can run Tkined as a
remote agent or server through rpc calls across the network? I did'nt
see much about it in the docs.
