I'll post this here in the hopes that it gets peoples' attention: You will almost certainly never see OpenOffice.org or any of its derivatives for the N8x0 for the following reasons:
1) size of codebase. It's huge and it's not getting smaller. This makes it difficult to work with.
2) size in terms of memory footprint. It brings a Mac with 512MB of RAM to its knees causing it to swap heavily. We have 128MB of RAM and no swap.
3) It is likely very difficult to compile for the ARM architecture since even Debian doesn't have a binary of it for ARM.
4) It's UI won't fit the screen size ... at all. and hildonizing it would be extremely prohibitive with regards to effort and changes vs the upstream codebase.

If anyone wants to prove me wrong and get it running, more power to them. In the long run though, I think that abiword and gnumeric are a much better bet.
