EditGrid is an online collaborative spreadsheet tool that I stumbled across via Ogle Earth. It strikes me thjat this could be a way to create phylogenetic data sets collaboratively.
As a quick test I grabbed the Vertebrates example file that comes with MacClade, exported the NEXUS file as a table, opened it in Excel, then uploaded the Excel file to EditGrid. You can see the results here.
The spreadsheet is a natural metaphor for phylogenetic data, although in this application is is likely to be better suited to morphological data where a team of people are assembling a matrix from various sources.
The developers of EditGrid have a blog whioch converys their own sense of excitement about this project.
