Here's a Coda-related tidbit that one of my students sent me.  I thought
people on this mailing list would find it interesting:

> I thought I must share this news item with you. Recently Google acquired
> DocVerse.com for $25M. Its amazing to see that the foundation of this
> online MS Office document editing service has principles not only inspired
> by Coda but seem infringed  upon from it. Its highlights are as follows:
>
> - It has local plugin(like Venus) which lets you edit docs locally (Coda
> client-cached copy) and saves a copy on the cloud ( Coda Server)
> - It allows multiple people to edit the same file at the same time (a la
> SVN, Git...)
> - It saves these documents by 'intelligently' syncing the changes and keeps
> version information (reintegration in Coda)
>
> They call this 'innovation'. Its a specialized and optimized(for Office
> docs) version of Coda. If you had patents on Coda, you could've blown the

Here's my reply to this student, reflecting my personal view of the role of
university research in society (and open source software):
