I think this is a matter of the size of data and not the "bushiness"
rows (fabulous term, btw).  For example, you could probably get away
with bushy rows to a certain degree if the columns themselves were
very small.

So you should probably approach this problem from a "how many MB do I
want to send in a single message" approach instead.  When the rows get
bushy, you should send less of them.
