bmon TODO/Wishlist 
==================

1: Differ between interactive and non-interactive output modules

	Currently the timing is done by sleeping in small amounts and
	check if the next read interval has been reached. The sleep
	amount gets adjusted to hit the next read interval as accurate
	as possible.

	This is only needed for interactive output modules. Non-interactive
	output modules could enforce a timing strategy which would sleep
	exactly to the next read interval and thus save some cycles.

2: XML Output Modules

	bmon's portability advantages could be used to provide all the
	architecture specific interface statistics and convert them to
	a generic XML based interface. There should be interfaces:
	
	b) State based

		The current state as it would be outputed by bmon itself
		written as XML message and overwritten in every output
		interval (just like the already implemented HTML output).
		This could be used by 3rd party applications to display
		the current statistics and rate estimations.

		Problem: Locking

3: SNMP Input Module

	A SNMP input module (secondary) would increase the usefulness
	in environment with properiatary hardware to which bmon
	cannot be ported.

	Problems:
	a) Async nature

		The whole module must be implemented async, this itself is
		not a problem but the protocol enforces various handshakes
		required to get the statistics:

		1) Get number of interfaces
		2) Wait for the result (could be cached)
		3) Request statistics
		4) Wait for the result
	
	b) Accuracy

		Due to the handshakes required the accuracy can vary depending
		on current network latency and it is quite hard to adjust it.
		Other statistical applications using SNMP don't have this problems
		because they don't require update intervals of <= 1 second.

5: MAPI Input (highly configurable)
