     Make the $value a string-only property again.

     It's a BC break that this might sometimes be a stream now. 
Instead make $value a setter/getter and add $stream property too. 
Convert between these two on the fly.
     Also make Horde_Db_Value_Text extend Horde_Db_Value_Binary 
because they share most of the code. This requires to change some 
class tests though, because "instanceof Horde_Db_Value_Binary" is true 
now for Value_Text objects too.

     Request: 10805

     Accept stream resources as the value of Horde_Db_Value objects.

     For drivers that can support it, will bind the stream resource as
     the data. Currently only implemented in PDO adapter.

I don't think this requires anything more than allowing an array of 
bound parameters to include stream values.  In other words, the array 
of bound parameters can contain a mixture of strings and stream 
resources.

Can you stub out what you'd like this to look like, from an API point of view?

Bumping priority.  As previously mentioned, this makes Horde_Db 
useless when handling any sort of decent sized data, unless the PHP 
memory limit is bumped to very large levels.  We are receiving a *lot* 
of feedback on the message lists from users that are running into this 
issue.

See ticket #10775.
