Rails spinoffs - Jul 2006 - [slightly OT] ajax calls, interpolating inbetween, moving ships and a map

Hello there,
since this is the greatest gathering of JS gurus all over the world, i have
a question not directly related to Prototype and Scriptaculous. I need to
mak a map of a certain part of the space (a system, sotosay). Displaying it
is not a problem, panning and zooming works great (thanks to prototype). My
question is mor design-related. In the sytem, i have spaceships that are
moving on a know route, (via backgroundrb) so the database is updating every
few seconds.
These changes shall be propagated to the user of the application, that works
well via ajax calls an PeriodicalExecuter. I dont want the resolution of the
executer keep as low as possible by interpolating the movement of the ships.
You see, thats a complex problem (at least for me, although i think im no a
bad programmer). and now my question: whats the best way to accomplish all
this? i dont want the complete sourcecode, i want some ideas, because i
think that my approach is ... unfitting, not to say shit.
How would you solve this? I really dot have any ideas anymore...

greets

Hmm, sounds interesting, any way we can log in to that link you provided in
your signature or see some example of the problem?

sure you can... just click "registrieren" on the login page, type in
some
stuff and you should be able to login. to get to the map once you''re
logged
in, clickon "navigation" in the menu. be sure to see the tiny plus and
minus
zoom links just above of the map, otherwise you can''t pan the map.
the map code can be found in http://stellar-legends.de/javascripts/slmap.js,
but its still undocumented
