I'd say supporting lzf AND lzo makes little sense, as its yet
another incompatible format (even if its autonegotiated, ensuring
interoperability), and your problem seems to have been licensing with lzo.
I'd recommend staying with liblzo (it is far more flexible) if you have
to support it anyways, but you can of course do what you want, I won't
complain if you find you want (my) liblzf in gnutls, I'd be honored :->
(I would also say that network bandwidth usually should take priority over
(reasonable) compression times, and liblzf is certainly on the speed side,
not on the data compression side, of the spectrum).

Yeah, but thats what the TODO list is for. In rxvt-unicode, for example,
whatever you put on the TODO list instead of tackling it immediately will
almost cetrainly stay there for years.

Go for it, and tell me any results, thank you :)
If you do them, the default is probably good, but you can look at lzfP.h for
configuration options, like:
HLOG - for memory usage, lower is less memory
VERY_FAST - enabled "medium mode", the default, which is good for binary,
somewhat bad for text
ULTRA_FAST - make it even faster, and quite a bit worse, ratio-wise.
One could even play with the hash function, which is critical, but the
default will certainly do.
