Sure! PostGIS database allows you this functionality. QGIS clients can edit in a concurrent way. You can test it connecting tow clients simultaneusly , when one of them is editing a vector the other one can see the results refershing the layer. PostGIS acts as other SGBD over the geom data as alfanumeric ones.
