Maybe it's priority is not that high, but I think it's an easy to use
log mechanism, especially when you don't want to do just debugging but
some analysis of the "real" behaviour of your code.
So as soon as I find time I will propose some patches.

No, it's seems to be no fall-back as there are no '*''s. The logserver
says that it will output to net, but does only output locally (even when
said '-nolocal'. And as said before no '*'.

I use not really another program, my grub config looks like this:

title vmware rt_sched deadline miss .211 
	root (hd0,1)
	kernel /drops/drops/bin/x86_586/l4v2/rmgr -sigma0
	module /drops/l4/kernel/fiasco/build/main -nokdb -nowait -serial -serial_esc -vmware
	module /drops/drops/bin/x86_586/l4v2/sigma0
	modaddr 0x02000000
	module /drops/drops/bin/x86_586/l4v2/names
	module /drops/drops/bin/x86_586/l4v2/log_net_lance -verbose -net -nolocal -ip -buffer 4096
	module /drops/drops/bin/x86_586/l4v2/dm_phys
	module /drops/drops/bin/x86_586/l4v2/rt_sched -l -m

(but even saying '-local' instead of '-nolocal' in log_net_lance gives the same

BTW: maybe writing to a file locally for logging would be easier, but as
far as I know there is no possibility to do so in DROPS?

Kind Regards,
