Localized Product Line is going to be the basis of a lot of combos, but just like Accelerated Diagnostics, it needs support cards to make it work.
The biggest limitation of LPL is that the corp must reveal the cards to the runner. This means tipping the other player off to the corp's intentions. This information makes it imperative that whatever operation based strategy is implemented in the same turn. This means using cards that give additional clicks.
Jeeves works well with operationas combos such as SEA/Midseason-Scorch.
Subcontract is an ideal combo piece as well.
Out of additional possibilities such as Efficiency Committee and Biotic Labor also arise, potentially allowing for fast-advancing a Vanity Project with a triple Shipment from SanSan.
Research Grant might verge upon usability with LPL, especially using a Jeeves-MirrorMorph-Shipment from SanSan combo, but the corp will spend the previous turn with 3 Agendas in hand, unless they use Biotic Labor to kick things off. A two-turn play might install one copy the previous turn and then triple advance the next turn, using Jeeves to MirrorMorph the other two copies before scoring all three.
Another interesting play is adding 3x Snare! to HQ and then playing An Offer You Can't Refuse. The corp can even spend the 3rd to a resource with the Snare! tag. With HQ Interface installed it may even be a flatline play.
Jackson Howard and/or Museum of History also combos with LPL to return up to 3 spent cards to R&D so you can use tutor them back to HQ.
