Supporting OOo WP format (.sxw, which falls under the broader rubric of XML, correct?) would be a fantastic boon for me, and for anyone else who uses Linux as well as OS X. It's pretty robust compared to RTF (including the RTF generated by NWE, which OOo does not always render properly; nor does Word). Why not implement it? More people would use it than the AbiWord converters, surely.
