What if connection points are added in user defined (and thus fixed) 
points, and Dia calculates percentage of each connection point's 
position and resizes sides keeping ratio taken from that percentage info?

E.g.:

1      2     3   4        5
*------*-----*---*--------*
0      30    50  60       100

goes to... (by ratio ~1.5)


1         2        3     4            5
*---------*--------*-----*------------*
0         30       50    60           100

Another way would be calculating equal distance between connection 
points after adding/removing a connection point.

E.g.:

*-------*-------*

You add 1 connection point. Dia reaaranges distances and therre it goes:

*----*----*-----*

Add 1 more:

*---*---*---*---*

Of course here pops up the first problem: how to handle one side of a 
box apart of other ones.

Am I too far from reality?
