[Zope] Persistent method

[Roelof Naudé]

Hi

Is it possible to have a persistent method/class/process running in the ZOPE
framework? For example an online trading site would have some connectors
(CORBA or XLMRPC) to an external system to do the trades. The connectors can
be a python class. This class will place an order and have to wait for a
reply, but since a reply can take too much time, one would have an
asynchronous call. The class/process still needs to stay resident so that it
can act on the reply, e.g. write reply to database/send mail to users etc.
Also it could monitor clients portfolios and send e-mail or some other
notification when a specific share is above or below a certain threshold.

Any suggestions?
