Coordinates of intersection

Hi, I am a long time user of MySQL but extremely new to the spatial extension. I am currently using server v5.5 becuase of legacy code. I hope upgrade to v5.6 soon. I have loaded a streets shape file (lines) to my MySQL database. Now I want to create a table I will use to search for specific intersctions.

This looks pretty easy. I created an intersection list with the following select:


SELECT a.roadname, b.roadname FROM gis.streets a, gis.streets b where(Intersects(a.shape,b.shape) and a.roadname != b.roadname);

But one more thin I want to include in the new table is the coordinates of the intersection. I can't figure out how to get that. I came accross the description of an Intersection(a,b) command that appears to do what I want, but evidently it doesn't exist in v5.5.
