It sounds like you have found a working chain for you. So, I found mine (-:
In fact I'm using repos and don't include "local-packages". And I've
never seen a binary hook or thought about writing one. So for my daily
work it works like a charm. I can make small edits without packing and
unpacking or something like this and in general I use it for storing the
image configurations, build and test them in intervals.
If I want to do bigger changes, I call lh_xml --import, work and test in
the config/ and pack it at the end with my lh_xml --export.
There is a question down there about not calling Import and Export. You
should check your mail programm. There was a file attached called
"lh_xml" without an extension (so modern mail software don't paste them
below the mail). The xml.sh is just a function (->
/usr/share/live-helper/functions/).
Maybe it will make a few things clearer.

At least we keep the original live-helper structure in the file. Maybe
even the lh_xml isn't the best example (that's all it is supposed to be).
A good structure would be to decide after a "lh_config -c" there should
be decided what function to use and lh_xml should be called lh_export or
something, with Attributes to maybe include binary, try to figure out
package versions, ...

browse images? on my build system?

100% correct. maybe an attribute worth, but default should be a complete
dump of the config.

see my first statement
sorry I cutted so many parts out, but the mail is way to long to read
anyway (my fault). but I have read and recognised it all.
thanks for the comments :-)
