An obvious desideratum is a full collation of all Greek manuscripts, freely available on the Web.
Can this be achieved and, if so, how?
It is possible for individuals and institutions to obtain images of the majority of known manuscripts (witness the collection of microfilms at Münster). There are usually no permission/copyright problems with producing an edition of the text contained within these manuscripts.
It should therefore be possible to obtain all the texts. The barriers to full collation are lack of personnel and finance. Here I have a suggestion.
It appears to me that we need a textual resource that is built up somewhat like Wikipedia. Perhaps using Wiki, or something similar, or even going through Wikimedia, contributors could gradually add material, for which they would recieve acknowledgement, but which would be freely available. I guess this would need some senior figure(s) within textual criticism to oversee and some who know something about technology. There would need to be editorial guidelines and the aim of achieving at least triple collation. Of course, without a burdensome system of checking contributions, it would not be possible to achieve the same level of accuracy as within the IGNTP and INTF collations. However, though accuracy is vital, a free tool like this can be constantly corrected and often something is better than nothing. Moreover, if a certain collator's collations were found to be unacceptably untrustworthy they could be removed, but if they were just occasionally unreliable then they could be supplemented by further collations. Each collation would come with the name of the collator (which should provide some incentive for accuracy) and if you spotted an error in a collation you could add a note in your name marking the error.
Clearly there would be a lot of work to do, but Wikipedia is surely a testimony to the fact that a useful tool can be created by creating a format into which contributions can be slotted. The editors would provide support by directing people to particular gaps (as here) and also by providing information on the whereabouts of manuscripts and addresses to contact. Otherwise contributors would be free to focus on what interested them.
I'm not going to begin this, so who is?
