[logback-dev] What is the most efficient way - preferrably platform agnostic - to submit events from "the outside"?

Not as such.  TCP/IP is very robust especially for dealing with these 
situtations, which is exactly what you are trying to avoid (so normally 
you would use UDP in such a situation like Quake and other multiplayer 
games do).

Are they?  How come?     Perhaps if using XMLEncoder instead of rolling 
your own :)

THe usual reason for using XML instead of a binary format is that you 
get the parser for free so you can go language agnostic easily.

Binary formats are rather painful to extend at a later date.  Just see 
how hard it is even with help from the serialization modules.

You may remember that I am in a situation where our production servers 
are inaccessible and where I want our logs to be both humanly readable 
as well as reprocessable.    I would be very interested in defining a 
very terse XML dialect for this purpose, as Ceki has demonstrated 
earlier that my needs cannot be fullfilled by the log4j dtd.

I see a good need for a production strength "xml receiver -> sfl4j 
events" added to the slf4j-ext package (or so) - would it licensewise be 
possible to adapt your work into this?
