if nobody has created a java 2 VM then you will not be able to install it

yes.
of course there must be a redmon replacement on other platforms.

yes.
i think about a sendfax.java with or without GUI

currently i am not sure how to do this in java.
can you give me a pointer on how to configure it in hylafax?

currently i have problems accessing hfaxd over subnets (see your FAQ!)
AFAIK the rounting on the server is not setup correctly to handle this.
did not have time to dig into this.

what are the advantages of active ftp  (is it called active?, is it
necessary for
masquerading?)

but i do not know how and if this can be done!
Dmitry, please, can you give me a hint?
I am pretty shure you know this :-)))

yes, true.
i think exactly about this, java supports dynamic class loading
(seee JDBC Manager, JNDI, ...)
also XML as a text file phonebook looks very interesting.

that's in mind but not in code yet. :-(
