  We analyze a recently proposed scheme to construct analytic lump solutions in
open SFT. We argue that in order for the scheme to be operative and guarantee
background independence it must be implemented in the same 2D conformal field
theory in which SFT is formulated. We outline and discuss two different
possible approaches. Next we reconsider an older proposal for analytic lump
solutions and implement a few improvements. In the course of the analysis we
formulate a distinction between regular and singular gauge transformations and
advocate the necessity of defining a topology in the space of string fields.
