David, This has been on my todo list for quite some time. I would imagine that for each session alias, you could specify a list of multiple table:column:class configurations such that if the table and column match, the class would be consulted to render the column value as a string. Obviously, this could be tricky for editing such columns (i.e. How to provide a GUI that lets you set properties on any generic object which is then serialized into the blob field as the original class type). But, at least for rendering, the implementation would be straight forward. The problem with that is the current plugin API only allows custom renderer's by session type and SQL data(column) type. Yet looking ahead, I can see that these new mappings might not be limited to being plugin-specific. So, a new core feature that allows you to map columns in certain tables to renderer's that can load classes to de-serialize BLOBs into Strings seems to be called for here. Feel free to submit a feature request for this.
