daniel,
i started to add support to mtree for integer values and allowing each node to have more that one value.
this would be much easier, it i would not need to support the currently undocumented MT_TREE_DW value type. can i drop MT_TREE_DW value type from the implementation or do you need it? if support for MT_TREE_DW is needed, it would be easier for me to leave the current module alone and write a new version of the module.
